QWE Activities (cont.) Human Capacity Building –Organize practical training programs, workshops and seminars for engineers and practitioners from Qatari industrial and governmental agencies on several aspects of water, environmental, and energy systems. –The emphasis is on “learning by doing” –We utilize the QWE existing world-class laboratories for these training courses. – We transfer the findings of our research to the classroom and, hence, give students a hands-on experience

Inland Desalination for Brackish Water with Zero Liquid Discharge  Inland desalination using reverse osmosis is a common practice  Brine discharge from inland desalination is a major environmental problem  Achieving zero liquid discharge will avoid the problems of brine disposal and maximize recovery  Available zero liquid discharge technologies are used mainly in industrial applications and they are prohibitly expensive for inland desalination  This project focuses in developing cost- effective and environmentally benign process for inland desalination with zero liquid discharge ZLD schematic diagram.

Advanced Reduction Processes for Hazardous waste Treatment  Chlorinated organics found in industrial wastes pose a global threat to the environment  Oxidation-reduction reactions are the primary method for destroying these contaminants  The requirement to achieve desired levels of destruction within a reasonable time is often not met  Unfortunately, there are currently no approaches available that are capable of cost-effectively destroying many persistent chlorinated organics.  This research aims at developing cost-effective treatment methods in order to enable sustainable operation of industrial processes while protecting the environment

Removal of Heavy Metals from water/wastewater using Reactive Adsorbents Recycle/reuse is one of the key solutions for efficient water management and minimizing environmental impact Heavy metals found in recycled wastewater are major challenge Adsorption is the primary process for heavy metals removal Residuals produced by the process are unstable when disposed in landfills They can leach to the environment after disposal Application of nano-particulate iron sulfides (FeS, FeS 2 ) Different removal mechanism; initial removal on the surface followed by surface reactions that would convert the toxic compounds to stable solid phase
